That's it, all right. volk_common.h defines a union which includes __m128i, which is only defined in SSE2 (emmintrin.h) and higher -- but the test Volk uses for this union is only (if LV_HAS_MMX). That test should be (if LV_HAS_SSE2). Ordinarily, on SSE2 machines, there's an #ifdef at the end of xmmintrin.h which includes emmintrin, where __m128i is defined. I don't know what making that change will break on non-SSE2 machines; can you try it? --n > > > > -- > Marcus Leech > Principal Investigator > Shirleys Bay Radio Astronomy Consortium > http://www.sbrac.org > _______________________________________________ > Discuss-gnuradio mailing list > Discuss-gnuradio@gnu.org > http://lists.gnu.org/mailman/listinfo/discuss-gnuradio _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
